I had been taking Bactrim for my acne for 6 days when last Wednesday I started getting the chills and a terrible fever. I went to instacare Thursday and they said it was nothing. I took my bactrim until Friday and noticed I was still sick. I've treated all my symptoms with ibuprofen which has helped my fever, but my lymph nodes behind my ears and on my neck are now swollen the size of golf balls. My neck is stiff and my skin is extremely itchy. My question is do I go to the emergency room or wait until I'm able to see my dermatologist again? I know it is my health and I should do what I feel but I don't want to pay a million dollars for something that will go away eventually.
